As you can see on top of
https://meta.wikimedia.org/wiki/Data_dumps, WMF is actively looking for help archiving and distributing data dumps. It would be great if you could check with the institutions you are associated with if they have available storage and bandwidth to donate. It would make it easier to keep better dump archives and improve downlaod speed. You can see more about the requirements
here. Ariel Glenn(in CC) will be happy to help anyone willing to host a mirror.
